Specification of Letters Patent.

Patented April 30, 1907.

Application filed ary 10,1906. Serial No. 300,493.

. q. .2 of the punch, as shoun in Fig. 1, Fig. 4, a

longitudinal vertical section through one of the jaws, and Fig. 5, adetailed end elevation of one of the riveting dies.

In all figures, similar letters of reference represent like parts.

This invention relates to punches, pliers and similar tools, and has forits object the production of tools of this class, with parallel movingjaws, having riveting dies so connected with said jaws as to gripobjects, the sides of which are not parallel, as, for example, thewooden strip at the end of a window shade. By having the jaws parallelwith each other continuously during their movement a punch may belocated on one jaw, which will project into or through the other jaw inwhich the article to be punched is held. But with jaws of this characteran objection has existed in that the riveting dies were incapable ofconforming to an article placed between them which did not have 5parallel sides. As in the present invention, the rlveting dies areswlvel mounted on the aws, they are free to turn on their pivots to griparticles of different form, as more par ticularly shown in Fig. 2, whilethe jaws of the punch moves, as hitherto, parallel to each other.

The invention consists, therefore, in the improvements and combinationsof parts hereinafter described.

Referring to the drawings for a more particular description, the partsdesignated by the letters A and B are lever handles, which at theirforward ends are forked, and are provided with parallel plates or tinesD and E which are fulcrumed together by the pin or rivets C.

The jaws F and G are pivoted at H between the forwardly extending platesD and E, and their rear ends extend into the hollow portions of thelever handles, with which they have a sliding connection, by means ofpins I, in well known manner.

The jaw G is provided with a punch K, projecting from the inner facethereof, through a perforation L, in the main portion of the jaw F. Thejaw F is provided with an arm M, projecting laterally from its upperside and extending forwardly and substantially parallel with the mainportion of the jaw. This arm M is provided with a perforation N inalinement with the perforation L for the reception of the end of thepunch K, when the jaws are closed (Fig. 2). A gage O is mounted on thejaw F, and provided with a thumb screw P adapted to clamp it in itsadjusted position.

The forward ends of the jaws F and G are slotted longitudinally, at Q,as shown more particularly in Fig. i. The riveting dies S are providedwith extensions R, which project into the slots Q, and are pivotedtherein by pins T. The dies S are adapted thereby to rotate on alongitudinal plane so that they may project directly toward each other,as shown in Fig. 1, or at an angle to each other, as shown in Fig. 2.

By this construction, an article, such as the stick in the end of awindow shade, the sides f of which are not parallel, may be perforated lby the punch K and eyelets may be inserted l and their flanged endsturned down flush or j made to conform to the sides of the article,whether the sides be parallel or at an angle j with each other. Asillustrated in Fig. 2, eyelets may be jnicely inserted in and theirflanges made flush with the sides of the lower strip of a l window shadewhich is thicker at one edge than at the other.

Having now described my invention, what -I claim and desire to secure byLetters Patextensions 10 to cooperate with said arm; and dies havingent, is

In punches, pliers and similar tools, the combination with lever handlesfulcrumed together ,of jaws operated thereby to move parallel with eachother, having longitudinal slots in their forward ends and one of saidjaws having an arm; a punch carried by one of said jaws and projectingthrough the other projecting into said slots and piv oted therein torotate in the plane of the tool, substantially as described.

In witness whereof I have hereunto set my hand on the 12th day ofJanuary, 1906.

WILLIAM A. BERNARD.
